What am I doing wrong with my holo script?

Okay, I have a training holo script that I wanted to change a little, and so I changed the keyvals that are said in the chat to load the map, and then I changed the name of the maps in the lighting to match the keyvals, but when I test it, the map will not load when I say the keyword combination "simulation initiate S-57" or any other map. What have I done wrong?

function globalScript(s)
yes = false
	for i = 1,#gs do
		if s.Name == gs[i] then
		yes = true
		break
		end
	end
return yes
end
 
game.Players.PlayerAdded:connect(function(player)
	for i=1,#trainers do
		if trainers[i]==player.Name then
		player.Chatted:connect(onDoorSpeak)
		break
		end
	end
end)
